Alchemy WDS setup

Running rc6 on a WRT54g v2.2. Need to bridge across the street. Tried a WRE54G, but couldn't get it to work with Alchemy WRT. I know there is a good WDS setup out here, but all I could find was the one for HyperRT. Is the setup the same? network...WRT54G 6rc6>....WRT54G 6rc6....PC
My network has a subnet of 255.255.0.0 so I couldn't run the stock firmware. Thanks
